Announcement to More Service Customers
Upcoming changes to More Service certificate on september 30, 2021
More Service uses Let's Encrypt for SSL. Let's Encrypt will change root certificate to ISRG Root X1 on 30. september.
If you are running Windows XP SP3 or newer, everything will work as before. The browsers Opera, Edge, Chrome uses the certificate store in Windows, and will be ok.
Firefox uses its own certificate store and updated versions of Firefox will also work without issues.
Be aware that external integrations should be verified to handle this change.
